Rattle proof anchor fitting for securing loads to a retainer track

Abstract

An anchor fitting has flat surface pads with shoulders extending therefrom and a post portion extending along an axis substantially normal to the flat surfaces of the pads. A latching plunger is slidably mounted on the post portion for motion along the longitudinal axis thereof. The fitting is removably retained in a selected position along a slotted track having a plurality of notched portions separated by narrow neck portions formed by flanges with the shoulders of the pads in the track slots underneath the flanges and the latching plunger member seated in one of the notched portions of the track. A cam bar member is supported on the anchor fitting in an apertured portion thereof by means of an adjustment screw. This bar member is drawn against the walls of the apertured portion of the anchor fitting such that it drives against the surface of the track drawing the shoulders of the pads tightly against the walls of the track to provide a tight rattle-proof joinder between the fitting and the track.

We claim: 
     
       1. In an anchor fitting for securing loads to a retainer track, said track having a top surface and a longitudinal slot and spaced notch portions separated by neck portions formed by a pair of oppositely positioned flanges, the anchor fitting having a pair of pad members positioned in the track slot under said pair of flanges and a latching plunger member positioned in one of the track member notches, the improvement being means for preventing the rattling of said fitting in said track comprising: an apertured portion having an arcuate wall formed in said fitting,   a substantially cylindrical bar member placed in said apertured portion, the diameter of said bar member being less than that of said apertured portion, said bar member having a first surface which abuts against the surface of the track and a second substantially cylindrical surface which abuts against the arcuate wall of said apertured portion, and   means for driving said second surface of said bar member slidably along the arcuate wall of said apertured portion and said first bar member surface slidably along the track surface whereby said driving action causes the first surface of said bar member to be cammmed against the top surface of the track, thereby causing the fitting to be driven upwardly relative to the track to bring the pad members into tight abutment against said flanges.   
     
     
       2. The device of claim 1 wherein said means for driving said bar member surfaces comprises a screw which threadably engages said bar member and which when tightened draws the second surface of said bar member slidably along the wall of said apertured portion. 
     
     
       3. The device of claim 1 wherein the first surface of said bar member is a flattened surface.
